Nova,
Thanks. What's happening is that I moved the temp sending unit to the head and the readings I get there go from 210 to 230F. The climb and drop reading there is erratic which leads me to believe that there is not a steady stream of water there but rather an air pocket. My fan control temp switch is located in the thermo housing where it was before I moved the sending unit. My fan used to come on when the water temp at the thermo housing reached 190 to 200F. Now it does not come on unless I override manually. And then the temp at the head does not drop.
